【摘要】 本文提出一种基于亮度匹配的灰度医学成像着色算法,将一幅(帧)待着色的灰度图像作为目标图像,用一幅(帧)彩色图像作为源图像,按行扫描目标图像像素,在源图像中搜索亮度最佳匹配进行自动取色,然后将其赋到目标图像上,最终得到结果图像,结果图像保持灰度图像原有的信息不变,而增加了源图像的颜色和真实感。实验结果表明,该算法在医学成像赋色处理中能够取得好的效果。更多还原

【Abstract】 In this paper, a general algorithm was introduced for rendering grayscale medical images by transferring color between a source, color image and a destination, greyscale image. The destination image was scan-lined to find a best match in the source image. And then the pixels were evaluated by the color of corresponding pixels in the source. The result image attained only chromatic information of the source image and retained the original luminance values of the target image. The images generated demonstrate the potential and utility of the algorithm in the medical image processing.更多还原
